IMPROVEMENT IN HUBS FOR CARRIAGE-WHEELS.

To all whom t may concern:

Be it known that I, HOLLAND E. Vrox, of Alliance, in the county of Starkand State of Ohio, have invented a certain new and Improved Carriage-Huband I do hereby declare that the following is a full, clear, andcomplete description thereof, reference being had to the accompanyingdrawing making part of the saine.

Figure 1 is a perspective view of the wheel or hub. Fig. 2 is a detachedsection. Fig. 3 is a transverse longitudinal section. The iigures onPlate 2 are detached sections to which reference will be had.

Like letters of reference denote like parts in the different views.

This invention relates to the hub of a carriagewheel; and the objectsought to be obtained is to so construct the hub that it can be securedto the axle at the posterior end by means of the axlecollar and atwo-part nut on the axle behind the collar, and which two-part nut isscrewed into the shell of the hub. The invention also relates to themanner of securing the axle-box in thev hub, -so that it shall be truetherewith, and also of a pair of collars or thimbles, whereby the spokesare clamped and thereby laterally braced. A more particular descriptionof the hub is as follows:

In the drawing, Fig. 3, A B represent a pair of 'thimbles or collars7detached views of which are shown in Fig. 4, in which it will be seenthat said thiinblesare each provided with a series of radiallugs,G,Fig.1,corresponding in number to thenuinbers of spokes D,andbetween which lugs the base of the spokes are clamped, as shown insaid Fig. I.

It will be observed, on examination of Fig. 3, that the outer end ofeach thimble is alike provided with a slightly-projecting iiange, a,thereby forming a kind of shallow recess. Into A ofthe thimbles isfitted the broad end of the screw-collar or thimble E, a detached viewof which is shown in Fig. 5, of which Fig. 6 is a transverselongitudinal section. In said Fig. 6 it will be observed that thethimble is provided with a female screw, F, the purpose of which willpresently be shown.

In the recessof collar or thimble B is fitted the head Gr of theaxle-box H,Fig. 3, a detached view of which is shown `in Fig. 9, and ofwhich Fig. 10 is a transverse longitudinal section. It will be observedthat in the head of the axle-box is cut a female screw, I, and that onthe end of the box Specification forming part of Letters Patent No.121,025, dated November 14, 1871.

is cut a male screw, J, corresponding in size to the screw F out in thethimble E, and into which it is screwed, as shown in Fig. 3. In thefemale screw I of the head of the axle-is fitted a two-part nut, K,Fig..3, a detached view of which is shown in Fig. 7, and of which Fig. 8is a transverse section.

The two parts ofthenut areheldtogetherbymeans of a ring, L, Figs. 7 and8, screwed on over the nut until it reaches the back end or shoulderthereof, against which it is screwed hard, thereby clamping the twoparts of the nut irmly together, as shown in Figs. 7 and 8, in which itwill be seen that a section ofthe nut projects beyond the side of thering L, and which nut corresponds in size to the female screw I, intowhich it is screwed, as shown in Fig. 3. To the inside ofthe thimbles orcollars A B is fitted a wooden hub or core, A', Fig. 3, a detached viewof which is shown inFig.2. In said core is fitted, in the usual way, thetenons of the spokes D, referred to, and which are braced laterally bythe lugs C of the collars A B, which are placed on each end of the coreand so adjusted in their relation to the spokes that they embrace thesides thereof, as shown in Figs. 1 and 3. The two collars are clamped tothe spokes and to the core by means of the axle-box, Fig. 9, which, onbeing inserted in the core covered by the two col lars, the thimble E isthen screwed onto the end J,

thereby drawing the two collarsA B toward each other and clamping thebase ofthe spokes between them, as shown in Fig. 3. By this means thecore, collars, thimble, and axle-box are firmly secured together and thespokes strongly braced laterally by the lugs C of the collars, and alsocircumferentially by them, as each lug is slightly concave transversely,as shown in Fig. 1.

The wheel is secured to the axle in the following in aimer: B', Fig. 3,is the axle, and G' the collar thereon. On that part of the spindle oraxle behind the collar the sections of the two-part nut are placed andscrewed thereon by the ring L, screwed on over the nut to the shoulderc, and which is sufiiciently large to pass over the collar G' of theaxle. A recess, D', Fig. 8, in the nut receives about onehalfl thethickness of the axle-collar C', Fig. 3, whereas the other half isreceived in the head G of the axle-box belouT the screw with theanterior side of the collar fitting close to the end of the box whichforms the bottoni or shoulder on the inside ofthe head, as shown in Fig.3. A leather washer may be interposed between the side of the collar andthe shoulder ot' the head of the axle-box, to prevent frictionalwearing, and the collar may be Wholly within the head G. On theposterior side ot' the collar C is also a leather washer, e, the purposeof which is to prevent frictional wearing of the collar.

It will be obvious, in view ofthe two-part nut being on the posteriorside of the collar C and the hub on the anterior side thereof, that onscrewing said nut in the head G of the axle-box forming 4a part of thehub the wheel cannot colue oft', it bein g held on the axle by theaxle-collar and the nut on the posterior side, and which is screwed, asaforesaid, into the hub. It will be observed, on examination of Fig. 3,that the collar ofthe axleis wholly inclosed by the nut and head oftheaxle-box; hence dirt and dust are excluded therefrom, so that frictionalwearing-of the axle in consequence ofthe presence of dust is avoided.

A wheel thus constructed and secured to the axle is neat in appearanceand is strong and durable, having the advantage ofthe elasticity ofthewooden hub, combined with the strength of the iron one. It also has theadvantage of being small in diameter and possessing the strength of oneof larger diameter, as the radial lugs C brace and support thc spokes asetfectually as a hub oflarge size. Then necessary, the wheel is easilyremoved from the axle by screwing out the two-part nut K, and

the nut can be taken from the posterior side of the collar by screwingoil' the ring L, and the ring in turn be slipped from the axle bypassingit over the collar, thus leaving the axle free of the Wheel andof any part of the coupling.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The collars or thimbles A B provided With radial lugs C and ilan gesa, formin grecesses in the ends thereof, into which are received thehead G of the axle-box and screw, collar, or thimble E, in combinationwith the wooden core A', axle-box H, and screw,collar, or thimble E,substantially in the manner as described, and for the purpose set forth.

2. The axle-box H having a screWei'1d,J, head G provided With afemale-screw, I, in combination with the collars or thimbles AB ofthehub and screw-thimble E, in the manner substantially as and for thepurpose specified.

3. The two-part nut K provided with an extern nal or male screw, Kl,recess D and ring L, as arranged in relation to and in combination withthe collar C of the axle B and head G ofthe axle-box H, in the mannersubstantially as described, and for the purpose set forth.
